Error in Making a List in a new object.

[Andrew Boyd]

Hi,
   I am currently trying to add a new object to my model during the simulation. 
 I have been able to successfully create the swarm object.  However when I try 
to execute the command to create a new list then I get the following error.

this is addCell test 1
this is addCell test 2
getNumComp Called in Cell.m 
createCompList called from Cell.m 
error: Zone_c.Creating (class)
Zone_c.Creating does not recognize allocIVars:
Abort

The first four lines are print statments verifying that the functions are being 
called.  If the list was created I would have recieved two print statements  
(See code below).

In Cell Model Swarm I call the function via:

  [nwcll createCompList];

where nwcll is the new cell object just created.


In the cell object the code is :
- createCompList
{
   [super buildObjects];
   printf("createCompList called from Cell.m \n");
   compList = [List create: self];
   printf("createCompList called from Cell.m 2 \n");
   return self;   
}

In the cell header file:

- (id)getCompList;                                // access methods into the

When first starting the simulation the object of cells can create a list within 
itself with the command:
   compList = [List create: self];
However during the simulation would you need to have another command to create 
a list?  I have looked in the Collection Library and the NeXT's developers 
library and have not found much on why I am getting this error.  Any and all 
help would be appreciated.
